Figure 9. Transmit enables and currents

After each cycle of current, the voltage in the resonating capacitor is less than the starting value due to losses in the antenna windings and resonating capacitor. This requires that the resonating capacitor be recharged before the next cycle. Figure 11 shows resonating capacitor voltage (100V/div), deactivation current (50A/div.), X coil charge, and deactivation enable signals. Deactivation While deactivate circuitry (H) is in standby (waiting Figure 11. Resonating cap voltage, for a label), the large resonating capacitor (G) is deactivation current, X coil charge, charged to a high voltage. Once a label is detected deactivation enable signal and successfully validated, the microcontroller triggers the deactivate circuit, which in turn, switches the capacitor across the antenna winding. This enables energy in the capacitor to transfer to the antenna winding for one half cycle and transfer back during the next half cycle, thus producing a sinusoidal current that flows between the capacitor and the antenna windings for a single cycle. As with detection, deactivation is multiplexed between the two antenna windings (designated X and Y). Figure 10 shows the X and Y coil current waveforms and the X coil enable signal. Because the output current is switched using SCR’s, the enable signal is set to ¾ of the current period since the SCR will turn off automatically once the current The top trace shows the resonating capacitor has reached zero (and not until then). voltage, the middle trace the deactivation current for both X and Y coils, the third trace the X charge enable signal, and the last trace the X deactivation enable signal. Note: The capacitor charges slightly before the first pulse and that the voltage reverses polarity as the current flows into the antenna winding and then returns positive as the current flows back out of the antenna winding.

Note: The final voltage is about 100V less than the Figure 13. Deactivation current, charge enable starting voltage. The capacitor voltage is then recharged before Y coil deactivation current is enabled (Y charge and deactivation enable signals are not shown and both the X and Y antenna windings share the resonating capacitor). Each coil is alternately triggered to produce the deactivation waveform. Figure 12 shows the high voltage output, deactivation currents, and charge enable.

Figure 12. High voltage output, deactivation currents, charge enable

As shown in Figure 14, ring down is controlled by changing the pulse width of the charge switch to only partially recharge the resonating capacitor between deactivation pulses.

Figure 14. Resonating cap voltage, Dx current, charge enable (CHG_XY)

As the resonating capacitor is recharged, the voltage in the high voltage storage capacitor begins to drop. This causes the deactivation current to decrease during the entire deactivation pulse. Approximately 200ms after the end of the deactivation cycle, the resonating capacitor is recharged. These recharge cycles occur during the transmit enable signal to prevent interference with receiver operation. The 200ms delay ensures that the deactivation switches (SCR’s) are completely switched off after the last current cycle. Figure 13 shows the deactivation current and charge enable signal at 50ms per division. At the end of the deactivation sequence the current decays to zero. This ring down ensures stationary labels placed over the pad are successfully deactivated.
